No. The ECU sends out voltage and measures resistance so it doesn't have polarity or anything. Can't hook it up backwards. The orange wires for the fuel pump are like that too. It doesn't matter what wire goes to the pump circuit and which one goes to the battery because the circuit between the 2 orange wires will be complete when the relay toggles.
